 ABSTRACT

A field experiment entitled “Effect of Sorghum hybrids on the growth and yield parameters as influenced by different nitrogen levels under rice - fallow conditions”was conducted at Agricultural College Farm, Naira (India) in sandy loam soil during rabi 2016-17. The treatments comprised of combination of four sorghum hybrids and four nitrogen levels laid out in Split plot design with three replications. Sorghum hybrid CSH 25 and application of 120 kg ha-1 recorded the highest growth parameters as well as number of grains per panicle. Significantly higher grain yield was obtained with CSH 25 among hybrids and with 120 kg N ha-1.However, stover  yield was highest with hybrid CSH 15R at 120 kg ha-1. Nitrogen uptake, agronomic efficiency, net returns and B:C ratio were also highest with CSH 25 at the highest level of N tried (120 kg ha-1) and hence found promising for North Coastal Zone of Andhra Pradesh.

Key words: Rice-fallow Sorghum, Hybrids, Yield, Agronomic efficiency, Nitrogen uptake and economics.
